Abstract
An improved pressure/temperature probe whose accuracy will not be affected by the pressures and temperatures to which it is subject or by the resistance of the connecting cables. The probe includes a separate pressure transducer and temperature transducer which are connected in series to a constant current source. In addition to the pressure reading taken by the pressure probe, a temperature reading of the pressure probe is derived from the pressure probe. This temperature reading provides the actual temperature of the pressure probe and permits highly accurate temperature correction. The pressure probe is constructed and arranged so as to have a high thermal time constant while the temperature probe is constructed and arranged to have a low thermal time constant.
